How to eliminate static electricity in non-metallic equipment and pipes
Thread Content
Hello, experts: In a certain fine chemical plant, most of the equipment is glass-lined. The process material pipelines are lined with PTFE or other non-metallic materials. Most of the materials handled are flammable liquids. How should static electricity dissipation be addressed in such circumstances? Please give me more guidance! Reply reward!
Foreigners have anti-static enamel; metal fibers are added to the enamel powder. However, it’s very difficult to manufacture and quite expensive. Regarding the equipment itself, it’s worth considering the installation of an electrostatic-dissipative insert tube. This foreigner also has the relevant technology for this purpose. If you want to ensure reliability, simply insert a corrosion-resistant metal rod into the tube to facilitate electrostatic discharge. The real challenge lies in dissipating static electricity along the pipes; usually, solutions are implemented at the flange connections.

What others have written in their reports is that \"steel-lined polytetrafluoroethylene pipes used for transporting flammable and explosive media should be conductive-static molded steel-lined PTFE pipes with graphite added.\"”
Combustion and explosion require two conditions, right: static electricity and oxygen. By controlling oxygen, nitrogen can be used to control the amount of leakage. Static electricity can be induced; platinum wires are used at the flanges, and an enamel tower is certainly not a single unit either – it is made up of multiple layers as well. At the joint, static electricity can be drawn off using a platinum wire.

This is also a solution; I’ve seen a company in the UK that uses an electrostatic monitoring system. This isn’t a conductive measure, but rather a monitoring system. A few years ago, I developed an antistatic solution for enamel piping systems for BASF; we were responsible for handling the entire pipeline system
I know that for using benzene as a solvent, this method is employed; it has been used for many years without any accidents.
International corporations like these pay more attention to the quality and stability of their equipment, focusing on long-term overall benefits; they are willing to spend money on that
We are all small regional companies; we don’t have money, and we’re even less willing to spend it.
